Abstract

A motorized vegetation trimmer apparatus (10) comprising an elongate main handle (12) to which is connected a motor (14) that rotatably drives a trimmer head (16) located at a distal end of the handle. The trimmer head (16) carries one or radially outwardly projecting cutting members (18) which cut vegetation as the trimmer head rotates. Each cutting member comprises a finite length of flexible strand. The cutting member is releasably gripped by a one-way gripping mechanism including a reciprocating gripping member (25, 152, 252) and a compression spring )50, 150, 250) that biases the gripping member into gripping contact with the strand.
